Chain hoist chain in the life of the period of use, the system will work for some time after the fracture failure, many people will not judge and test the nature and causes of the chain fracture, the lifting chain fault occurred in different parts of the different factors, if not Timely exclusion, the system security will cause great harm.
Article Summary:
Although the lifting of the chain are generally 80 grade Φ7.1mm and Φ11.2mm low carbon alloy steel material, not only in safety, toughness are very good, but sometimes can not stand the outside world and the impact of human factors, so there are For the following reasons:
1. Improper operation, not in accordance with the synchronous electric hoist instructions on the operation of the operation, in the operation caused by damage in the invisible, over time will break.
2. Overload use, not in accordance with the synchronous electric hoist signs on the load lifting, increasing the bearing capacity of the chain, resulting in chain breakage.
3. No maintenance, no time to smear the oil chain, a long time the chain rusty dry.
4. The new chain and the old chain used together, resulting in the operation process, resulting in impact, it is easy to pull off the chain.
To reduce the occurrence of synchronous electric hoist chain fracture, we should do the following:
1. There is dirt on the chain, should be cleaned immediately, rather than wait until the maintenance phase in the clean-up.
2. timely oil operation, to prevent the chain appears dry,
3. Synchronous electric hoist chain tightness to adjust to the appropriate state, to prevent the chain is too tight, there are chain jump and towline situation.
4. Regularly use the vernier caliper to measure the length and diameter of the chain, the abnormal should immediately replace the chain.
Here or to remind you, if the synchronous electric hoist chain break, do not install their own. This will only increase the risk of accidents.
